All HerculexTM hybrids contain LibertyLink® technology, making them tolerant to over-the-top applications of LIBERTY herbicide for powerful weed control.
LibertyLink®

- Non-selective herbicide that controls over 120 grasses and broadleaf weeds including weeds resistant or tolerant to Roundup® as well as Roundup Ready volunteers.
- No known resistance to its unique mode of action.
- Combines excellent crop safety with fast-acting control.
- Rotate with Roundup Ready® to manage weeds and resistance.
- Fast-acting contact herbicide. Symptoms of weed death are visible in as little as one or two days.
- Broad-spectrum control of broadleaf and grassy weeds, including mustards, buckwheat, lambsquarter, pigweed, kochia, wild oats and foxtails.
- Leaves future cropping and herbicide options open because there is no residual soil activity.
- Postemergent control offers flexibility in application timing, so you can tailor your weed control program to your needs and schedule - and keep costs down.

Herbicide Tolerance
Hybrids containing HerculexTM Xtra technology are resistant* to Liberty®
herbicide when applied over-the-top in accordance with the Liberty®
herbicide label.

herbicides such as Liberty® herbicide from Bayer. This herbicide gene will NOT safeguard
this hybrid against application of other herbicides. Accidental application of other herbicides
to this hybrid could result in total crop loss.
